Instructions/pix for installing COMAND Aux cable?



I know how to get the COMAND unit in and out no problem, and know how to remove the top inside bit of the glove box, but beyond that cannot tell how the aux cable gets threaded "behind the scenes" from the back of the glove box to the back of the COMAND unit.
Does anyone have the MB instructions for how to do this, or can can tell me whether I have to take anymore bits of the car to thread this cable, and how to do so.
PS: this is not the iPod cable installation I'm talking about.
Thanks in advance for any and all help!
